Question

There are 34 people in a restaurant. Four groups of 3 people leave, and then

5 groups of 2 people arrive. Evaluate the expression 34 4 3 5 2 −•+• to
determine how many people are in the restaurant.

Answer 1

There are 36 people in the restaurant after the groups leave and arrive.

Step-by-step explanation:

To evaluate the expression 34 4 3 5 2 -•+•, we need to follow the order of operations (PEMDAS/BODMAS). First, we perform any multiplication and division from left to right. So, we have 4 × 3 = 12 and 5 × 2 = 10. Next, we perform any addition and subtraction from left to right. So, we have 34 + 12 - 10 = 36. Therefore, there are 36 people in the restaurant after the groups leave and arrive.
